-WINDOW.

SPECIFICATION forlning part Of Letters Patent N 0. 671,642, dated April 9, 1901.

Application filed August 30, 1900. Serial No. 28,486. (No model.)

T0 all whom it Wray concern:

Be it known that I, WILLIAM CURTIS TAY- LOR, a citizen of the United States, residing at Ridley Park, Delaware county, Pennsylvania, have invented certain new and useful Improvements in Windows, of which the following is a specification.

My improvements, while applicable to windows of all ordinary descriptions, is particularly adapted and intended for use in connection with car windows,and I have accordingly, in the accompanying drawings, illustrated it as employed in connection with the form of window frame ordinarily resorted to in car construction.

As is well known, the sashes of car windows and blinds, owing to the tendency of the side walls of the car bodies and the thin sashes themselves,to become slightly bent or warped, very frequently become so tightly wedged or bound in the window frames that it is a matter of -great difficulty for passengers to raise or lower them.

It is the object of my invention to provide a car window sash of such construction that it will run smoothly and freely in its ways in the frame, regardless of any ordinary change of relation of the frame to the sash incident to any sagging or bending of the adjacent struc! ture of the car body, or swelling or warping of the wood of the frame.

In the accompanying drawings -I show, and herein I describe, a good form of a convenient embodiment Vof my invention, the particular subject matter claimed as novel, being hereinafter definitely specied.

In the accompanying drawings,

Figure l is a view in front elevation of a window frame and sash embodying my invention.

Figure 2 is a sectional plan on the line II of Figure 1. A

Figure 3 is a fragmentary perspective View of one of the corners of the sash.

Figure 4 is a view in top plan of a window sash and a blind sash, both constructed in accordance with my invention, in position in a window frame, shown in section. l

Similar letters of reference indicate corresponding parts.

In the drawings, 1 indicates the frame of a window, assumed mounted in the body of a car, steamboat, or other structure, and embodying in its respective opposing faces the V-shaped grooves 2, illustrated in Figure 2.

The Window sash 3, with its pane of glass 4, normally fills, when down or closed, the entire opening of the window frame,eXcept space for play of the springs.

Within the body of the wall in which the window frame is 1ocated,and above said frame, is the usual sash boxing or recess into which the sash (or sashes when two are employed as in Figure 4.) enters when raised,said recess beingin Figure 1,indicated by the dotted lines 5.

It is to be understood that while the window sash may, as shown in Figure l, contain Vinvention is concerned, identical with those forcontaining the glass. When two sashes are employed in one frame, as in Figure 4, one, 3, for glass, and the other, 10, for a blind, two sets of V-shaped grooves 2 are of course formed in the window frame.

The sash embodying my invention is, as to its respective side edges, beveled or tapered off, so to speak, to formwhat may be termed V- shaped beads, 6, such beads being engaged within the V- shaped grooves of the window sash, a space being left, however, between the respective beads and grooves, for the springs, and for their elastic accommodation to the changes always threatening the channels of the frames and the edges of sashes.

Each of the respective side edges of a sash is provided with two spring plates, 7, disposed in approximately V-shaped relation to each other, and preferably supported upon the sash. Said spring plates are preferably continuous from the upper to the lower end of the sash, and each while fiXedly secured as to one edge, is free as to its otheredge, so as to be of considerable resilience and flexibility.

Each pair of spring plates is provided at its inner edge with a supportingplate, 8, conveniently, as shown in the drawings, formed as an integral continuation thereof, the two supporting plates of each pair of spring plates IOO being entered in a supporting plate incision 9, formed in the side edge of the sash and opening through the V- shaped bead referred to.

When the supporting plates are entered in the supporting plate incision referred to, the spring plates are, of course, iirmly supported as to their inner edges, while their outer edges set out somewhat from the respective faces of the V-shaped bead, and consequently, present against the respective faces of the V- shaped groove 2, in which they are entered; manifestly, therefore, the sides of a sash bear against the sides of the window frame only through the four spring plates described, and the bodies and outer edges of said spring plates being normally at some distance from the corresponding faces of the sash, any swelling of the Wood of the window frame, or any slight torsion of said frame, will merely deflect said spring plates somewhat toward the solid portions of the sash, without interferring with the freedom of the sash for movement in its Ways, inasmuch as said torsion or change of relation of the frame is taken up by the yielding of the spring plates.

The spring plates furnish smooth and easily moving faces, so to speak, for the sash, under all circumstances.

The amount of space which normally exists between the edges of the spring plates and solid portions of the sash is a matter to be determined by constructors.

When two sashes are employed in a single Window frame, as shown in Figure 4, I prefer to construct said frames in the manner illustrated in said ligure. One of the side members of the frame is formed as a solid body with the two grooves cut in its substance,in

the other side member a suitable recess 16 is formed, in which are mounted the blocks 11 and 12.

In applying the sashes, the blocks 11 and 12 being out, the sash 3, is first placed in position, the block 12 is then put in place and secured by screws 14; the sash 10 is then placed in position, and thereupon the block 11 is put in place and secured by screws 13. The block 11 has an ornamental facing, having an extension which projects out over the sash 10, to cover the crevice at the edge of the groove 2; and an ornamental block 15 applied to the other side member of the window frame, has a corresponding extension which projects over the edge of the sash 10 to cover the crevice of the adjacent groove 2.

Having thus described my invention, I claim:

1. In combination, a window frame and a sash, a V-shaped groove formed in one of said devices, and two spring plates mounted on the other of said devices in approximately V- shaped relation and projecting into said V- shaped groove, each of such spring plates being free as to one edge and supported as to the other edge, substantially as set forth.

2. In a window, in combination, aframe embodying V-shaped grooves at its sides, and a sash provided at each of its respective side edges with a pair of spring plates arranged in V-shaped relation, each of said spring plates being free as to one edge but as to its other edge provided with a supporting device secured to the sash, substantially as set forth.

3. In a window, in combination, a frame embodying V- shaped grooves, and a sash the respective side edges of which are each provided with a vertically extending supporting plate incision, a pair of spring plates disposed at each of the respective edges of said sash, each of said plates being provided with a supporting device entered inl said supporting plate incision, substantially as setforth.

4., In a window, in combination, a window frame, the opposing sides of which each embody a V- shaped groove, and a sash the respective side edges of which each embody a V-shaped bead longitudinally through each of which beads extends a supporting plate incision, spring plates mounted on the respective side edges of said sash, and each provided with asupporting plate, entered in said 'supporting plate incision, substantially as set forth.

5. In a window, in combination, a window frame, the opposing sides of which each elnbody a V- shaped groove, and a sash the respective side edges of which are each provided with a V- shaped bead, longitudinally through each of which beads extends a supporting plate incision, spring plates mounted on the respective side edges of said sash, and each provided with an integral supporting plate, entered in said supporting plateincision, substantially as set forth.

6. A sash having an incision in one of its sides, a pair of spring plates Adisposed in V- shaped relation at said side, anda pair of supporting plates, formed as continuations of said spring plates and entered in said incision, substantially as set forth.

7. A sash provided as to its edge portion with two spring plates secured thereto, the bodies of the spring plates being arranged in approximately V- shaped relation, substantially as set forth.

8. In combination, a window frame and a sash, a groove formed in one of said devices, and a pair of spring plates disposed in angular relationship to each other, mounted on the other of said devices and projecting into said groove, each of said spring plates being free as to one edge and supported as to the other edge, substantially as set forth.

In testimony that I claim the foregoing as my invention I have hereunto signed my name this 23d day of August, A. D. 1900.
